Can someone please help us adjust the jandy valves for optimal performance on our pool? It is a 33,000 gallon lazy l with a vinyl liner. It has a spa with overflow, heater, and Polaris pump. Also, it is a salt water system (not sure that matters for this question). I can't quite get the valves right. Either the overflow halts or is very slow thereby allowing debris to settle in the hot tub (as well as staining). I'm assuming the valves are properly labeled. (I keep trying to upload a picture, but I don't think this is allowing it.)
